To allwkom it may] concern: v

Be it known that I, JACOB KAUFMANN, a

citizen of the United States,, residingfat.

Philadelphia, in the county of Philadelphia and State of Pennsylvania,- have invented certain new and se m Improvements in Hedd'le-Frames, of; which the 'following isa sp'ecificationi y i My invention relates to heddle frames for looms and it has particular relation toan My invention contemplates agheddle frame which will be light yet strong and durable and in which foulingof adjacent frames in the loom" will be reduced to a'minimu rn.

Heretofore most heddle frames have been made with the to'p and'bottom rails of wood i and in some instances'these top and'bottom rails have been "connected at their'ends by means of relatively thin flat metal 'end bars and in other. cases the rails have been joined at their ends by wooden strips. Wherefthe end bars have been inade of thin'flat metal it often occurs that'the corners 'ofadjacent frames will foul on each other byreason' of the negligiblesurfaces of the end bars not affording any or a sufficient guide for each other. On the other hand where the end bars are made of wood the joints'qui'c'kly become loosened because of the constantly shifting strains to which the structure is subjected when in use. The object therefore of my invention is to provide a heddle frame in which the defects of the two types of heddle frames above mentioned will be largely eliminated. A further object of my invention is to generally improve the construction of the heddle frame as will later appear.

The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1 is an elevational view of a heddle frame embodying the main features of my present invention;

Fig. 2 is an enlarged fragmentary detail view, partly in section and partly in elevation, illustrating the construction of one of the corners of the'frame;

Fig. 3 is an end elevation of the portion of the structure shown in Fig. 2;

Figl t is a horizontal section of one of-the 5is a perspectiveview' of a fastening material and connected at their ends by bars or strips 7 likewise-formed-ofwood' or similar material. The end bars 7' are the strip '7 and is bent over at eachend'as at '10 extending over the outer margin of the "The strips '7 are securedorbracedtothe innercorners of the top and bottomrails -6 bymeans of bracing members "12shown =in detached perspe-ctive in Fig. 5 of the drawings; These bracing members are each formed from a strip of thinfiat metal, one endof which is'bent over asiat13 for. seating the same securely in the groove 14 suitably located near the inner corner of the end rail 6 and the member 12 is secured to this portion of the rail 6 by means of a wood screw 15 which passes through a suitable aperture 16 in the strip 12. The fastening member 12 is also provided with a bent portion which forms a shoulder '17 in alinement with the end of the rail 6, and from the end of the shoulder 17 there extends a tongue 18 which passes through a suitable aperture 19 in the bar 7 andstrip 9 and has its end portion 20 bent over on the outer surface of the metal strip 9 to securely fasten and brace the end bar 7 to the inner corner of the rail 6. a

The" end bars 7 and similarly the strips 9 taken on the'line H of Fig.- 2;

It will thus be seen that there is provided i a; fight yet durable form of heddle frame i'n which the Wooden end bars '7 are suitably reinforced by means of metal strips 9- which metal strips also afford a durable and con-- venientmeans of attaching the end bars 7 to theendsof the top and bottom rails 6. The metal strips 9 also provide hard bearing portions for the proper mounting of'theheddie-barsand; their attachments .in the end bars 7.
